"The bail petition is dismissed," Justice S Harish Kumar said in his order.
Mohammed Nalapad Harris, son of N A Haris, was booked for attempt to murder for allegedly assaulting L Vidwath during a brawl at a pub-cum-restaurant in U B City here on February 17 night.
During hearing of the bail plea, counsel for Vidwat submitted that the attack on his client was ghastly and hence the petition must be dismissed.
A sessions court had earlier rejected Nalapad's bail plea on March 2.
The Congress MLA's son at present is in judicial custody.
Nalapad and six other accused were sent to Parapana Agrahara Central Jail after a city court awarded a 14-day judicial custody for further interrogation.
The MLA's son and the others were arrested on February 19 when they surrendered at the Cubbon Park police station.
The incident had created a political storm, prompting the Congress to suspend Nalapad from the party for six years.
Nalapad's father had also tendered an apology in the state legislative assembly over the issue.
